What is the BOM header?
The BOM header is placed in the header of the UTF-8-encoded file, which occupies three bytes to identify the file as being UTF-8-encoded. Currently, many software programs recognize BOM headers, but some cannot recognize BOM headers. For example, PHP cannot recognize BOM headers, this is also the reason for the error after the UTF-8 encoding is edited with notepad.
How do I remove the BOM header?
The easiest way to remove the BOM header is to use software such as editplus or ultraedit. The details are as follows:
1. Use editplus to remove the BOM Header
After the editor is adjusted to the utf8 encoding format, a hidden character (BOM) is added before the saved file, which is used by the editor to identify whether the file is UTF-8 encoded.
Run editplus, click the tool, select preference, select the file, select the UTF-8 ID alWays Delete the signature, and then the PHP file after editing and saving the PHP file is without Bom.
2. Use ultraedit to remove the BOM Header
After opening the file, select from the encoding format in the SAVE as option (the UTF-8 has no Bom header) and OK.
